Five hundred patients with successful pancreatogram between 1982 and 1990, 8 patients (1.6%) were found to have complete pancreas divisum. The sex distribution was equal (4 men, 4 women), and the average age was 42.5 years (22-77 years). No increased incidence of pancreas divisum in any of the three groups: a group with pancreatitis, a group with unexplained upper abdominal pain, and an incidental group (obstructive jaundice, gall bladder disease, abdominal mass, miscellaneous). These findings show that pancreas divisum is a normal anatomic variant with an incidence of 1.6 per cent in Thai patients, and is seldom a cause of pancreatic symptoms.
